Assembly structure of magnetic clutching device of cord bracket for window blind

Abstract

An assembly structure of a magnetic clutching device of a cord bracket for a window blind, particularly referring to a cord bracket for supporting a cord at a midway of a top rail and an assembly structure of a magnetic element of a magnetic clutching device corresponding to a first slide seat, includes primarily metallic magnetic pieces having hook plates at their back ends for constituting a magnetic element. By latching the hook plates into a latching slot in the cord bracket, and with a latching and holding function formed at corner ends of a permanent magnet in a front part of the magnetic pieces, objects of positioning in a three-dimensional orientation and a dry assembling can be achieved.

1 . An assembly structure of a magnetic clutching device of a cord bracket for a window blind, more particularly referring to a cord bracket for supporting a cord at a central section of a top rail of a window blind, and an assembly structure of a magnetic element of a magnetic clutching device installed corresponding to a slide seat, comprising primarily a cord bracket provided with a latching slot for latching a magnetic element which is constituted by a block of permanent magnet whose two sides are stuck with magnetic pieces; a latching hole located at a back side of the latching slot for latching at least one magnetic piece by hook plates at rear ends of the magnetic pieces, and wrapping edges formed at corner ends of the permanent magnet, in a front part of the magnetic piece.  
   
   
       2 . The assembly structure of a magnetic clutching device of a cord bracket for a window blind according to  claim 1 , wherein wrapping edges are located in a front part of the two magnetic pieces, in corner positions of the magnet, respectively.  
   
   
       3 . The assembly structure of a magnetic clutching device of a cord bracket for a window blind according to  claim 1 , wherein at least one hook tooth is located at the hook plates of the magnetic pieces.  
   
   
       4 . The assembly structure of a magnetic clutching device of a cord bracket for a window blind according to  claim 3 , wherein the hook teeth are symmetrically located at an upper and a lower position of the hook plates.  
   
   
       5 . The assembly structure of a magnetic clutching device of a cord bracket for a window blind according to  claim 1 , wherein at least one concaved hook edge is located at the latching hole at a back side of the latching slot.  
   
   
       6 . The assembly structure of a magnetic clutching device of a cord bracket for a window blind according to  claim 5 , wherein the hook edges are symmetrically located at an upper and a lower position of the latching hole.  
   
   
       7 . The assembly structure of a magnetic clutching device of a cord bracket for a window blind according to  claim 1 , wherein stress absorption grooves are opened inside breadths of the magnetic pieces, at positions corresponding to the hook plates.  
   
   
       8 . The assembly structure of a magnetic clutching device of a cord bracket for a window blind according to  claim 1 , wherein slant pushing edges are formed at external sides of the hook teeth of the hook plates.
